MileDown MCAT Biology Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the role of the myelin sheath in neural transmission? The myelin sheath insulates axons, allowing for faster transmission of electrical impulses along the neuron through saltatory conduction. Describe the process of endocytosis in cellular transport. Endocytosis is a process where the cell membrane engulfs extracellular material, forming a vesicle that brings the material into the ce...

MCAT Biology Chapter 1: The Cell Questions and Answers What are the four tenants of the cell theory? - Correct Answer️️ --All living things are composed of cells. -The cell is the basic functional unit of life. -Cells arise only from pre-existing cells -Cells carry genetic information in the form of DNA Why are viruses not considered living organisms? - Correct Answer️️ -They violate the cell theory; -their genetic material is RNA -they cannot reproduce on their own, they must ...

MCAT Biology | Latest Version | 2024/2025 | Already Graded A What is the role of the endoplasmic reticulum in protein synthesis? The endoplasmic reticulum aids in protein synthesis by providing a site for ribosomes to translate mRNA into proteins and assisting in the folding and modification of these proteins. How does the Na+/K+ pump contribute to maintaining cellular membrane potential? The Na+/K+ pump maintains the cellular membrane potential by actively transporting three sodi...
